Woven Resin Brake Lining Rolls
Woven resin brake band is a high-performance friction material, mainly composed of a fiber woven structure and resin composite. It is widely used in braking systems of ships, engineering machinery, mining equipment and other fields. The following is a detailed introduction:
1. Materials and Structure
Fiber Framework
High-strength fibers (such as E-Glass fibers, aramid fibers, brass wires, etc.) are used to form a three-dimensional network structure through an overall weaving process. The inner layer is usually a mixed weave of E-Glass fibers and copper wires to enhance tensile strength; the outer layer uses a high-temperature-resistant acrylic fiber woven layer to improve surface wear resistance. This multi-layer composite structure not only ensures flexibility but also can withstand high shear forces and impact forces during braking.
Resin Impregnation
The woven fiber framework is impregnated with specially formulated polymer resins (such as phenolic resin, epoxy resin) and undergoes high-temperature and high-pressure curing treatment. The resin not only fills the gaps between fibers but also combines with fibers through chemical bonds to form a rigid matrix, significantly improving the material's hardness, high-temperature resistance and wear resistance.
Weaving Process
Plain weave piling or multi-layer mixed weaving technology is adopted. For example, plain weave piling locks the layers through mixed threads, avoiding the looseness and fault problems of traditional weaving; ultra-thick brake bands are woven by multiple groups of weft yarns crossing at different angles (0°, 15°, 30°) to further enhance thickness and structural stability.
